NOTE
Getting Your Feet Wet
numbers in the formatted string. You can use either function in your C++Builder programs,
but sprintf() is preferred because it has full floating-point support (and it’s one less character
to type!). To get a real appreciation of what sprintf() can do for you, consult the C++Builder
online help.
Arrays of Strings
Not only can you have character arrays, but you can have an array of character arrays
(effectively an array of strings). That might sound complicated, but you have already seen this
type of array in the ARGSTEST program we looked at earlier. You can allocate this kind of array
as follows:
char strings[][20] = {
“This is string 1”,
“This is string 2”,
“This is string 3”,
“This is string 4”
};
Although you can use this type of string array, there are easier ways to handle arrays of strings
in C++Builder. (I’ll save that discussion for after you’ve had a chance to learn more about
C++Builder.)
Summary
If you are going to use arrays of strings extensively, you should look
into the Standard Template Library (STL). STL provides C++ classes
that allow you to store and manipulate arrays of strings much more
easily than is possible using C-style character arrays. STL also includes a
string class.
You’ve covered a lot of ground today. First you tinkered with the C++Builder IDE by
creating a GUI Hello World program. Following that you were introduced to console mode
applications where you created Hello World, Part II. After the initial playing around, you
were put to work learning the basics of C as a foundation to learning C++. You have learned
about the following C and C++ features:
■ Variables
■ Operators
■ Data types
